WebIn science and engineering, hydraulic conductivity (K, in SI units of meters per second), is a property of porous materials, soils and rocks, that describes the ease with which a fluid (usually water) can move through the pore space, or fractures network. It depends on the intrinsic permeability (k, unit: m 2) of the material, the degree of saturation, and on the … WebJun 24, 2015 · Permeability is controlled by such factors as pore size and pore-throat geometry, as well as porosity. To take some account of these factors, the widely used Timur equation [2] relates permeability to irreducible Sw and porosity, and therefore can be applied only in hydrocarbon-bearing zones.
WebJan 14, 2024 · The gut microbiome regulates essential functions for the maintenance of general human health. It influences the immune system and homeostasis both locally (within the gut) and systemically.
